About: amazing video: deep coal mine in Poland


Brilliant video,and this reminds me of the old "R.O.L.F." [Remote Operated Longwall Face ],units which were pioneered down south in the Nottinghamshire pits,in England ,UK.,about 40 or 50 years ago,[?].
Systems like this would have been buried on the first shear,down the Three-Quarter [R] Seam of coal,at Bates Colliery,in Northumberland,England,UK.
When we first started developing the seam,the first bog standard Shearer faces would take a shear at 42" high,and the roof pressure broke and flattened up to 70 face chocks all at once in a massive roof fall....and I MEAN Flattened!!..all legs pushed forward,and down over the A.F.C,with the canopies flat on top,completely buried.
So much damage that it would take three weeks to replace all the chocks,timber up to 15' high above the canopies,having to stand on top of the canopies,to built "Butts" with hardwood chocks and baulks,to reach the exposed roof,after all the fallen roof stone was ridd..
This went on so long,on every face won out,to a distance of 800 yards advance,until Bosses finally took advice from US the miners on the face, risking life every time we crawled up the face,to just abandon the faces,and drive forward about 60 yards,then win out the faces anew.
From then on,the faces were surviving the tremendous roof pressures,and the pit was making a profit when thatcher was so bent on killing the industry,that we went down along with all the rest.
I wonder if the success of this face,and pit,survived,very long,after ripping coal out at record levels...! Bravo to the lads ![ Check out my pics of Bates pit on Flickr].
Great mo.vie . Love the automated system with the operator safe and dust free. Can you tell me how you detect a mechanical failure for instance a broken relay bar pin on a shield ? Through my experience underground , even on a fully manned face these small things can cause a lot of grief. Again great movie and mine that coal i love it
Congratulations polish miners..!
I hope you will keep your mines in Silesia more than 40 years...

Hi, great video. I have done 2 short movies concerning mining in South Wales on my Youtube channel "UAV PAP". I hope to do more when time and weather permits.
too many faults in our old pit for the system to work but in the right conditions like these it's a great system
Wonder howmuch russia miners nake an hr compared to us miners
Nice


Coal stock


Coal is extracted from the ground by coal mining, either underground by shaft mining, or at ground level by open pit mining extraction.

Languages:

Coal is primarily used as a solid fuel to produce electricity and heat through combustion. World coal consumption was about 7.25 billion tonnes in 2010 The price of coal increased from around $30.00 per short ton in 2000 to around $150.00 per short ton as of September 2008. In early 2015, it was trading near $56/ton.
